Letters Patent No. 110,983, dated January 17, 1871.

IMPRQVEMENT IN MACHINES FORlVlANUFACTURlNG HINGES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, WILLIA l Lewis, (assignor to the Bnxsnio'jr 8: BURNHAliI Manufacturing Oompany,) of Waterbury, New Haven county, Connecticut, have invented, made, and applied to use a new and useful Machine for Inserting the Pintles or Pins in Butt-Hinges; and that the following is a full, clear, andexact description of the same, reference being bad to the accompanying. drawing making part of this specification and to the lettersof reference marked thereon, in whichfor inserting pintles in butt-hinges.

Figure 2 is a side view of the same, the -platesfoi" supporting the hinge being removed.

Figure 3 is a front viewof-a portion of the machine, showingthe pintle being inserted in a butt-hinge.

In the drawing like parts of the invention are designatedby the same letters of reference.

The nature of the present invention consists in the construction, as more fully hereinafter set forth, of an improved machine for, inserting the pintles or pins in butt-hinges.

Herctofore the wire of which the pintle is composed has been fed into the machine, where it was cut olf of the proper length,and then driven into the hinge; in such machines the wire is apt to be bent, and, at times, it has been found difiicult to feed it into the hinge after it has been catch" in the machine.

My machine is constructed with a view to employ pintles or pins previously formed, which are supplied through a hopper, and, having been so supplied, are

.forcedor driven into thehinges, as more'fully hereinafter explained, thus overcomingthe difficulties heretofore existing and'accomplishing the work efficiently and rapidly.

To enable those skilled in the' arts to make and use my invention, I will describe its constrnctionand operation.

A shows the base of the machine for supporting its operative parts. This plate A has a portion of its face cut away to form a way, in which the sliding plate B moves li-eely to and and fro, and also to receive a block, 0, groo'cd upon its face, in which groove the pin or pintlc is fed from the hopper D, as more fully hereinafter set forth.

The base A has a portion of its face cut away to form ways in which move the sliding plates E, upon which the butthinge rests, and is held, the butt portion of the hinge, being held between'these plates E.-

'D shows a hopper, formed of the V -shaped sides properly seemed together, which hopper is intended to receive the pintlcs or pins to be supplied to the machine. The metal in the manufacture of these sides is turned over and projects suflicicntly to prevent the pintles or pins from leaving the hopperD nmil fed therefrom.

upon the base A by cutting away a portion of the same,

which sliding plate G slides or-moves between the plates forming the hopper D, above a'portionof the block 0 and up to the groove in the same. Figure l is a front view-of my improved machine Upon the forward end of the sliding plate B is secured a driver, H, by which the pintle or pin is driven into the hinge.-

Upon the face of the sliding plate-B is secured a cam-shaped piece, J, intended to operate a bent lever,

, K, by which the sliding plate G is operated. [This bent lever or arm Kis pivoted upon the base A, andone end is slotted and passed over a pin secured in thesliding plate G, while in-its opposite under side is secured a pin, 0, having its bearing upon the camshaped piece J. v i

L shows a flat spring, one end of which is secured upon the base A, while its opposite end is curved so that it shall have a bearing upon the end of the lever or arm K; this spring may be attached in any other form to, produce a like result.

'Secured upon the base A, directly in front of the hopper I), so that its face shall be slightly behind the groove in which the pintle or pin is received, is a' gauge, M, intended to form a guide, so' to speak, for the driver H, and also to prevent the pintle leaving the machine while being receivedfrom the hopper 1) or while being driven by the driver H.

Secured about centrally upon one of the clamps employed. to connect, together the;v sides of the hopper '1), is a flat spring, N, extending nearly to the bottoni of the hopper, and beneath which the sliding plate passes when the machine is in operation.

Between this spring N and the plate F the pintles or pins are received as they are fed'down from the upper portion of the hopper D, the sides forming, when properly secured in position the hopper, may be slotted at the points intended to receive the screws,

so that the sides may be adjusted to difi'erent-sized pins or pintlcs.

Such being the construction the operation may be,

thus set forth:

The hopper D is first adjusted to the sized pintles it is desired should be used, andthc pintles are then supplied to the hopper, which may be tilled with them,

the lower or bottom ones resting bet-ween the inclined back plate F and the spring N. The block G is now adjusted in position, so as to bring the groove in the some in line with the butt upon the hinge by means of the set-screw b, and the regulating screw .0 inserted in one end of the base A, and against which -avatar],

i), upon the under side of the plate 13; impinges, is adjusted so as to govern the movementof the plate B, and thus determine the distance'that the driver H upon the sect-ions of binge to be united are nowreceived between thes'liding plates E, the butts projecting down through the same, while the-balance 0tt-he-hinge restsnpon I the plates E. The sliding plate .13 is now forcedforward, and as the earn-shaped piece npon' the same is brought to' bear npon the pin a secured in the arm K the same is moved forward, by-which movement of the arm a backward, movement'is given to the oppo site end,-whieh', as already stated, is slotted and passed over arpin secured in the sliding 'plate G, and the-forward'end of this sliding plate G iswvithdrawn from Z beneath thespringll, jtista sui'ficient distance toallow one pin or pintle toldrop down'between The forward movement ofjthe plate B conthe sliding plate B, and as the cam-piece upon the:

same is withdrawn from contact with the pin in this sliding plate, the spring L, which, by the forward movement of the arm K, has been compressed, ex-

forward endof the same will 'travel. The

pands and causes the arm K to return to its former position. In retnrnin g, to its former position a forward movement-is given to the slotted end of thearm passed over a pin secured in the'sliding plate G, and as a se 'quence this plate-advances, its forward end impingingnpon the pintle or pin fed down directly in front of it, and carriesor forces the same forward to and into the groove in the block 0, whence it is forced out and into the hinge by the next forward movement of the hamnicr,-as already described, the hinge into which the former pintle has been driven having in the meanwhile been removed and its place supplied by aseeond hinge. It will thus be seen how rapidly and certainly. the pins can be fed from the hopper, carried up to the groove, and driven therefrom andinto the hinges.

Having thus described my invention,

'What'I claim as new, and desireto secure by Let V ters Patent, is-' The combination, with the base A, of an adjustable hopper, D, sliding plate, G, sliding plate B, provided with-a hammer, H, grooved block 0, and springs L and N, and arm K, when the same shall be constructed and operate substantially as and for the pur-.

poses set forth. 7
